Another new drug for MS. What I find interesting about Ocrelizumab is that it was originally being tested as a drug for rheumatoid arthritis but stopped because of an “association” with infection. How far is it shutting down the immune system that it was causing infections? I would think this is a red flag for future cases of PML.

On the plus side taking Ocrelizumab only twice a year has to reduce the risks significantly for dangerous side effects. The article I saw compared it to the safety of Rebif, I am highly skeptical of that claim. Though if it is as safe as they claim it would be a great drug, and everything we had hoped for from Tysabri.
